What this shows Purewick's Innovation Score is 52.5/100 (top 10% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Purewick?

Each dot is one of Purewick’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Purewick’s own 17.6 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Purewick's grants concentrate

PureWick Corporation is a focused PatentsView assignee: 13 CPC subclasses with 88.9% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2024 (20 grants) versus a trough of 1 in 2020. By volume, Purewick sits between Origin Wireless, Inc. and Robert Bosch Automotive Steering LLC.

Purewick's three-year grant acceleration

PureWick Corporation shows 29 grants in 2022–2024 against only 13 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
